Title: (EN) SPRUNG SEAL RETAINER
Abstract:
(EN) A combination valve and coupling has a retainer in the form of a ring which engages a seal. The seal engages the valve closing member and is captured within a pocket in the valve housing by the ring. The ring has tabs in spaced relation about its outer perimeter which engage dogs on the valve housing to retain the ring in contact with the seal. The stiffness of the tabs may be tuned to provide flexibility to the ring and permit the seal to deform when the valve is opened and closed. The tabs have angularly oriented surfaces which engage the dogs and cause axial motion of the ring upon its rotation to adjust the preload between the ring and seal.
